Germ layers and the body cavity
Slice through four body plans and see the germ layers and whether a body cavity (coelom) is present.
What to notice
In a pseudocoelomate the mesoderm forms scattered pouches, so the cavity is not fully lined by mesoderm.
Key relation
Coelom = body cavity lined by mesoderm
Try this
Compare the pseudocoelomate and coelomate sections — where is the mesoderm?
What you can change
- Body plan: choose Diploblastic, Acoelomate, Pseudocoelomate, Coelomate
